Installation Notes

Windows’ Smart Screen may block the installation. You can disable the Smart Screen from the Control Panel.
The User Account Control may block / warn against the installation. Ignore or click “more info” to proceed.
Contact us if you’re in doubt – and we will verify that the install files are still 100% OK.

If the program doesn’t run normally, you may need one or two of these:

Minor bug fix to preserve length of measurement ir for higher sample rates. It was unintentionally reset to 44.1/48 length at a stage in the correction algorithm. The bug sometimes affected filters at high sample rates.

Audiolense 5.1 (64 bit)

Audiolense 5.1 (32 bit)

MIcrophone calibration can now be embededded and sealed in the measurement. Old method still works, though.

A few changes to improve the robustness of the new TTD correction algorithm.

We recommend that all users install the new version and keep the old one just in case.

[20 jan 2008]

Audiolense 1.2.2941.26985

Time alignment resampling bug fixed. The time alignment was not properly resampled earlier.

[8 dec 2007]

Audiolense 1.2

Now with a complete rework of the measuremodule – including support for Asio, Direct Sound and Windows MME. In addition:

The measurement bandwidth is further improved. Even the shortest measurement at 44,1 kHz will now be ruler flat to over 20 kHz. The measurement procedure is much faster. We have speeded up the generation of measurement files and the impulse response generation. Use Asio if you can. If not, try MME and Direct Sound and pay attention to the high frequencies. Use the one with the largest measured bandwidth if there is any difference.

We recommend that all users install the new version and keep the old one just in case.

Audiolense 1.1

Note: Old measurements will not load.

Major improvements in the measurement module: The bandwidth of the measurement has been improved. Even the shortest measurement duration now produces full 20Hz – 20kHz measurement with 48 kHz sampling.

96 kHz and floating point measurement is now working. Enabled user to choose to record from left, right or from a mono mic input. This will prevent noise from open inputs to creep into the measurement.

Revised the directory structure. User can choose default directory, and each Audiolense revision x.x will be installed side by side with old revisions.

Minor improvements in the filter correction procedures: Changed the “longer” correction procedure in 2.0 and Surround version to account for a longer time window of the measurement. Improved frequency smoothing function. Implemented polarity check in the measurement procedure. Low passed drivers will be inverted when required by the XO.

Various visual improvements and visual bug fixes: Added manual y axis control in several charts. Moved the “Filter measurement” button one step up the ladder.

Improvements in the target designer: Target location can now be adjusted in height (but it will not affect the correction filter). Fixed target designer bug that caused troubles when Audiolense wa set to 96 kHz sampling. Improved the targets’ stopband performance.

* The number of correction filters on complex setups with bass management has been optimiced and reduced.

* Boost limiting was limiting too much on speakers with high spl in the treble region. The boost limiting is now more based on the true average sensitivity of the speaker / driver

* Minor changes to

New functionality:

* Individual correction of parallell /partly parallell drivers are now supported (just turn on the XO verification box in the XO setting tab)

Audiolense 0.9.2722.4625 (beta)

Fixed:

Bugs fixed that will be vital in some setups. Errors in the speaker setup detail section that could influence the correction procedure has been fixed.

Improved exeption handling in speaker setup details. Such as when the user deletes a subwoofer that another speaker is using.

[June 07. 2007]

Audiolense 0.9 (beta)

Known issues:

On Windows Vista beta there has been problems with playback of measurement signals with some sound cards. The problems are depending on the choosen sampling frequency in Audiolense and the audio setup in Vista. Sofar we have always had sucessful measurements when Vista is set to 44.1kHz default and 44.1kHz is used for measurement in audiolense.

There are minor discrepancies between some of the helpfile illustrations and the applications.

Unusual command sequences have been known to cause program errors. to cause program errors.

The official release of Audiolense 5.0 has arrived. The correction engine in Audiolense has been substantially redesigned. Among the main results are improved crossovers and time domain correction. More details in the download section.
